PDF file. REVERSE is a puzzle game that we think you have not seen before. REVERSE, as described in this 80-page eBook, is mostly missing from the Internet. Opportunity knocks! You and we together can develop REVERSE as a NEW tool/toy for learning and teaching math.

Many first-time players find REVERSE a boggling game and are unable to solve the puzzle until – Aha! – they discover or invent a method that works for any list of numbers. We describe algorithmic and heuristic methods for playing REVERSE. We think REVERSE is a great game for you and your students to explore and contrast algorithmic and heuristic problem solving. Hey, it's a game - kids love games.

This eBook also introduces Double REVERSE, a NEW puzzle game inspired by REVERSE. We hope that you will encourage students to discover or inventways to solve REVERSE and Double REVERSE puzzles.

We are just beginning to explore Double REVERSE. Help develop REVERSE and Double REVERSE as tools/toys for learning and teaching math.
